Larry Fink and BlackRock don’t own the 6% of Google managed by BlackRock index funds. Nor does Google or other co’s decide to make adverse decisions to their morale and productivity because of a very minority shareholder. What you’re describing is conspiracy theory.
Occam’s razor. These co’s came to the same conclusion co’s like OpenAI did, that in persons benefits outweighed the negatives. Only when the conclusions don’t agree with the preferences people like you have, that the cope, conspiracy, and rationalizing come out. Also, what may be good for the individual, doesn’t mean it’s good for the org.
